IMPROVEMENT IN MACHINES FOR MAKING PAPER COLLARS.

Specification forming part of Letters Patent No. 46,34 0, dated February 14, 1865.

To aZZ whom, it may concern:

Be it known that I, MERRIMAN P. DoRsoH, of the city, county, and State of New York, have invented a new and useful Improvement in Machinery for Cutting and Embossing Pal per Collars; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a front elevation; Fig. 2, a horizontal section taken at the line A a., Fig. l 5 Fig. 3, a face view of the upper die; Fig. 4, a vertical section taken at the line B b of Fig. l; Fig. 5, a vertical section of the'diiving wheel or pulley, taken in the plane of the axis of the driving shaft and Figs. 6 and 7 cross-sections taken at the lines C c and D d of Fig. 5.

riEhe same letters indicate like parts in all the figures.

The object of my invention in machinery for cutting and embossing shirt-collars out of paper is by an intermittent motion to feed or move forward the sheet of paper to the required places between the cutting and the swaging dies, and there hold it while these operations are being performed.

In the accompanying drawings a represents a suitable frame, and b the bed'which forms the lower pressface or die, c, and what may be termed the female 7 portion of the shears. The lower die, c, is simply a flat smooth face of metal. I prefer to make it ofsteel. There are three apertures, ddd, made in it, of theform of the button-holes required to be made in each collar. These holes should be formed with sharp square edges.

A mortise, f, of the size and shape of the intended collar, is formed through the bed c, leaving the upper edge square and sharp, and this forms ywhat I term the female 7 part of the shears. To this mortise is accurately fitted a plunger, g, which forms the male portion of the shears. This is secured 'to the under face of a follower, h, which is t-ted to slide in suitable ways, i t', of the frame, so as to slide accurately therein, and the lower face of this plunger g is beveled in opposite directions from the middle toward each end, so as to give the cutting-ed ges thereof, in entering the mortise or female part of the shears, a shearing cut, so that by this and the accuracy with which it ts the mortise the collars will be cut with a perfectly-smooth edge vand without bending the paper, thereby avoiding a serious d ifculty heretofore experienced.

The face of the follower h by the side of the plunger is provided with an embossing-die, c2, whose surface is smooth and parallel with the face lof the die or bed c, and this is provided with three punches, d d d, so as to accurately fit in the apertures d d d in thebed to punch the button-holes, and this emboss`- ing-die c2 is formed with a groove near the edge, which corresponds with the edge of the collar, to which groove are fitted the plates c3 c3 which emboss the imitation of stitching.

The follower receives an up-and down motion from an eccentric, j, on a horizontal shaft, lc, or the required motion may be given by other and equivalent means.

The required motion is given to the main shaftkby a belt-wheel, Z, which receives motion by a suitable belt from some suitable motor. Itis necessary at the end of eacli complete series of operations to stop the machinery while the belt-wheel l continues to 1nove,`and it is important that the stoppage should take place in every instance at the samepart of the ran ge of motions. For this purpose the hub of the belt-wheel l is mounted to turn freely but accurately on the shaft and between collars m and n--the one m being a shoulder on the shaft and the one n a circular plate on the outer face of the belt-wheel, but connected with the shaft so as to turn with it.

After the hub ot' the belt-wheel has been properly litted tok turn on the shaft, a cylindrical hole, o, is bored parallel with the axis ofthe shaft, and partly in the shaft and partly in the hub ofthe wheel, and into this isviitted a turning stop, p, having a journal at one end iitted to turn in and extending through the outer collar or plate, n, and projecting sufficiently beyond the outer face to have attached to it an arm, q, by which the stop p, can be turned. The periphery of the stop pis so cut away that when in the position represented by full lines in Fig. 6 its outer surface will be like a continuation of the cylindrical part of the shaft, on which the belt-wheel will turn freely, and in that position of the stop the e X- tremity of the arm q will be in the position represented by full lines in Fig. 7 ofthe drawings; but when the .arm q is moved inward toward the axis of the shaft, as represented by dotted lines in Fig. 7, which is effected by the tension o f a spring, r, the stop p will then be turned in the position represented by dotted lines in Fig. 6 of the drawings, and in that position it will clutch the belt-wheel to the shaft, and thereby communicate motion to the machinery.

The required motion for turning the Stopp to unlock or uuclutch the belt-wheel, is imparted to the arm g against the tension of the spring r by its coming in contact with a camt'ormed spur, s, projectihg from the inner face ofa boss, t, which slides 011 the outer end ot' the main shaft, which is there of a reduced size. This boss is forced toward the face of the plate n by the tension of a helical spring, u, on the sha-ft, and when so pushed inward the camlike spur s is placed in the path of the arm q, so that in its revolution it (the arm) strikes the cam-surface by which it is moved outward to turn the stop p to the position rep resented by full lines in Fig. 6, thereby unlocking the belt-wheel, that it may continue to turn without the shaft.

The boss t is on the end ot' an arm, u, of a rock-shaft, w, which has another arm or handle, fr, hy which the attendant can draw back the boss t with vits cam-formed spur away from the path ofthe arm q,'so as to leave it free to be operated by 'the tension of the spring r,to lock the belt-wheel so soon as that portion of the hole o which extends into its hub reaches the stop p, to admit vof its turning.

B y the proper relative location of the eccentric on the shaft, the hole o, made in the hub of the belt-wheel and in the shaft, the arm q ou the stop p, and the camlike spur on the boss t, the machinery will stop at the required part of its range ot' motions while ,the beltwheel continues to run, the operator sirnply drawing out the boss at any time.

The feeding motion for moving the paper is taken from the platen or follower l, from which project two brackets, a a', which are connected by connecting-rods b b with two arms, c c, of a rock-shaft, d. From this rockshaft project two other arms, e e', the upper ends ot' which are formed with concentric seg nlentslots, f j", which receive pins g g that project from the ends lof a bar which constitutes the front part of the feedingframe, composed of two side pieces, h L, and two end bars, t" i. This feeding-frame slides on the surface ofthe bed to which the bed-die is secured, and

between ways 7" 7", and undertwo cross-plates,

L and l, one of which acts as` a clearer to prevent the cutter from drawing up the paper.

The inner edges of the side pieces, h h', of

'the feeding-frame are grooved longitudinally to receive the edges ofthe sheet of paper and to permitit to slide therein, and they are both of them cut away at top to receive and permit spring gripping ngers m m lo grip and hold the sheet of paper near the two edges. These spring-fingers are so formed that when the feeding-frame moves in the direction ot' the arrow (see Fig. 2) they will grip the sheet so as to move it towardand between the dies and slide over the sheet as the frame moves back to enable them to take a fresh hold of the paper for the next operation, the sheet being held, as the frame moves back, by similar gripping-ngers, m2 m2, attached to the crossplate k2. The range of motion of the feedingtrame is equal to the width of a collar-that is, equal to the width of paper required for each collarand by the motions of the feeding-frame the end of the sheet of paper is first brought under the embossingdies, there held until it is embossed, and at the next motion the embossed part is brought to the cutters, cut ott', and discharged below, and, by the same motion, a fresh portion brought under the embossing-die.

As the motions of the feedingframe arc `derived from the platen or follower which carries the cutter and punches to cut out the button-holes, and these in making a collar not only pass through the paper but into the beddie, it is necessary that the follower with its cutters should rise sufficiently to get out be.- fore the feeding-frame begins to move to feed the paper forward. It is for that reason that the arms e e of the rockshaft d are formed with segmentvslots j" f', to receive the pin-s g g of the bar 'i' of the feeding frame, sothat the said arms can move for some distance, as the platen is rising, before they act on the feeding-frame. The other arms, t c', of the rock-shaft d are formed with slots a, in

which are secured the wrist-pins that formy the connection with the counectingrods, so that by shifting the wrist pins the range of motion ofthe feeding-carriage can be adjusted to any width ot'collar required to be made.

What I claim as new, and desire toy secure by Letters Patent, is v 1. The reciprocating feedingframe with the sides thereof grooved to receive the sheet ot' paper, in combination with the grippingtin gers, substantially as described, and having a mode of operation such as described,and for the purpose specied.

2. The reciprocating` feeding-frame with its gripping-fingers, operating substantially as herein described, in combination with the dies for embossing and cuttingV the collars,l substantially as described. i
